MACHINE FOR THE PRODUCTION OF HORSEHAIR THREADS.

Application filed June 16,

To all whom it may concern:

Be it known that I, FRrrz Monrus, a,

citizen of German residing at Gross-Kolzig, in the Province Brandenburg, Germany, have invented certain new and useful 1mprovements in Machines for the Production of Horsehair Threads, ofwhich the following is a specification. V

"his invention relates to an improvement in machines for the production of endless horsehair threads and more specially to the feeding device. The feeding device con-V sists of a horsehair coming from the reservoir, a

needle opposite said finger, a pair'of feeding cylinders and a bow designed to insert the horsehair between the feedingcylinders; The finger serves as abutment ,for theneedle and for the horeshair and bears from the rear against the bundle of horsehair. The needle is moved from the front towards the bundle of horsehair and the finger to grip. one or several hairs of the bundle, whereupon the needle and finger move downward 2 to pull the hairs out of the bundle and eon-v duct them to. the feeding cylinders. When the finger and, the needle have moved. down to between the conical heads of the cylinders they move away from, one another to release the horsehair pulled out of the bundle.- This horsehair enters at first between the conical heads of the cylinders and is then drawn between said; cylinders by means of the inserting bow, the horsehair being .thus gripped by' the cylinders and fed to the spinning machine, that is to say to the spindle of same.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming-a partof this specification, with the understanding that wh' e on the drawings one embodiment of the invention is disclosed, the invention is not confined toany strict conformity with the showing of the drawings, but may be embodied in any manner which does not make ajmaterial departure from the salient features of the invention.

r In the drawing:

Fig; l-shows the machine in side elevation in the position when the needle is ping one or several horsehairs and pressing the same against the finger.

finger serving as abutment for the 1923. Serial No. 645,755.

Fig. 2 shows the feeding device in plan View.

F i ing the severalparts in the finger and needle are inserting the pulled out horsehair-between the conical heads of the gripper cylinders. Fig. 4L shows the different parts in the position when the. needle and the finger have moved away from the feeding cylinders and the inserting bow is conducting the horsehair between the feeding cylinders by which it is gripped and conveyed through a funnel to the spinning machine.

The operating parts of this feeding device are the abutment or support for the threads to be pulled out ofthe bundle 2 of horsehair; the needle 3 which moves towards said finger and descends together with-the same thereby pulling one or several threads out of the bundle 2 of horsehair and bringing the same to the gripper cylinders 4:, 5; thesaid 4, 5 and the inserting bow gripper cylinders 6. These parts operate in the following manner:' 1 r The finger 1 is adjustablyiarranged one end of a lever 7 pivotally mounted on a pivot pin 8. The rearward extension of the lever 7 isacted upon rotated in the direction ofv arrow 12 from a driving shaft 11; The pivot pin 8 of lever 7 is mounted in a sliding block 13 adapted to execute a reciprocating movement between the straight guides '14. The movement of the sliding block is controlled by means of a rod 15 pivoted on a crank arm 16' carried by the drivingshaft 11. The'sliding block 13 carries further a two armed lever 17 18in the arm 17 on which the needle 3 is mounted, the other arm 18 of saidlever bein acted upon by the cam shaped end 19 of t e crank arm 16 designed to oscillate said two armed lever 17 18. A spring 20 attached on'the one hand to rod 15 andon the other hand tothe arm 18 of the lever serves to hold said lever against the cam 19. From g. 3 is a similar view to 1 show-,

the position when finger 1 'which serves as an by. a cam disc 10 the chain wheel 21 of driving shaft 11 anoth chainlwheel 23 is rotated by means of chain 22, said second chain wheel 23 rotating through-the intermediary of a bevel wheel 24, a small bevel wheel 25 gripper cylinder keyed on the end of the 4. The other gripper cylthe end.

guides inder 5, opposite gripper cylinder 4 is mounted on an arm 26 which pivotally mounted; on a 'pinfQI. "on the. frame. 28 and pressed by the action of spring 29 to hold. the cylinder 5 against the gripper cylinder 41" '1I1gri er= cylinders are grooved on their circumference so thattley grip at their rotation the horeshair threads to them and convey theiii' 'through 'the funnel 30 to the spinning machine, The gripper cylinders 4 and 5 have conical pointed heads &- SQ that the. horsehair threads pulled out of bundle 2 may be inserted between the gripper cylinders by means of the feeding ow 6. The feeding. bow 6 consists of a wire. loop; (Fig. 2) pivotally mounted at of. lever 7. A movable arin32 of this feeding bow 6 slides .upon a. rail 33 which. determines. the. position of the .feeding bow 6. With "regardto. the gripper cylinders 4: 5.

The. bundleQ of horsehair projects from a. box. 34, convenientlyv fixed on the frame 3 5; of themachine.

The operation ofthe feeding device is s. followe i I On "rotation ofthe driving shaftv 11 in the direction Qfthe arrow 12 the cams 10 and 1,9; are moved to permit the finger 1 to. be pressed from behind against the bundle 2 offhorsehair and; the needle 3 to descend,

tpwards the finger 1 so that they grip between themone or several horsehairthreads (Eig'ill;

The crank. 16.nextv causes the advance of the. sliding block 13. between the. straight 14, the needle 3 remaining in contact. with the finger 1. The horsehair threa-diclamped. between the finger land he needle. 3 are thus pulled out of the bundle 2 and conveyed towards the gripper cylinders 4, 5 the sliding block 13 moving in such a manner that the finger 1 and the needle are brought between the conical, heads of the gripper cylinders 4 and 5 (Fig.3). i

lVith the forward movement of theslidingblock 13 the feeding bow 6 is also moved forward above the gripper cylinders a, 5, so that the horsehair been pulled out of the bundle by the needle, and brought to the gripper cylinders are situated in. the feeding bow 6 between the conical heads 31 of said gripper cylinders.

The arm 18 of lever 17, 18 is then pushed back-.by the, action of cam 19 (Fig. at) and they needle 3; is raised from the finger 1, whereby the horsehairthreads are released.

The sliding block 13' is then pulled back between the straightguides,ltthrough the actlQnofcrank 16, whereby the finger and the needleare both pulledv back, thetwo parts being however no longer in engagement. The feeding how 6 is simultaneously drawn back and. catches the released horsehair threads, which have.

drawing the descending ends of the same between the. conical heads 31 of the gripper cylinders 4 and '5 and finally between the gripper cylinders (Fig. 4).

As the gripper. cylinders rotate in opposite directions they v'ey'thesam'e tothe feeding funnel 30 and wa squen ly. t the spinnin device Where t ey are spun in the usual manner together with the feeding. thread and the Winding threads.

This feeding device works in a very simple and reliable manner as thehorsehair threads are clamped between the finger "1' and: the needle 3, these two tools being simulta; neously moved in sucha manner that the pulled out horsehaircthreads are inserted between the conical heads of the gripper cyl inders, whereupon the feeding bow brings the horsehair threads securely "between: the heads 31 of the'cylinders 4, 5, so that they are securely gripped by the said cylinders; The number of horsehair threads gripped by the needle depends on the width of the point ofthe needle.
